Eva Fernanda Ordonez is a third-year student at UC Merced and wants to help students plan their daily commute to campus or the community. She used online surveys to study the barriers to sustainable solutions for travel and why students are not using the current system. By remodeling the Fleetmatic mobile app, Ordonez says that more people will commute together by bus, reducing individual vehicle emissions, improving air quality and student life, if the app and bus schedule is upgraded.

Our homes and buildings consume huge amounts of energy – up to 40 percent of all energy use in the US. Research at Berkeley Lab has greatly boosted energy efficiency in buildings but the challenge now is not just how much energy we use, but when we use it. We need to shift loads to times when there are plenty of renewables in our electric system, and reduce load at other times of the day. New technologies will get our energy production and our energy consumption talking to each other. Series: "Cal Future Forum: Our Changing World" [Show ID: 33078]

Fossil fuels have powered economic growth and improved quality of life for more than two centuries – and for good reason. They can store a great deal of energy, and it can be used any time. The challenge for the scientific community is how to gain flexibility from renewable sources. Ravi Prasher and his colleagues have pioneered efforts to use computing power to discover new materials. His group then synthesizes the materials, and finally makes devices to test in the real world. He stresses that researchers are doing what they must: moving toward a future when we can assure steady, flexible, economical clean energy.

At a time of uncertain water supplies, how can we get the most use of our water? By passing water through a material called a reverse osmosis membrane, adding a small amount of hydrogen peroxide and exposing it to ultraviolet light, engineers in Orange County, California have been turning what used to be considered useless wastewater into drinking water for more than 25 years. David Sedlak’s research team at Berkeley has developed technologies to improve the treatment processes. Series: "Cal Future Forum: Our Changing World" [Show ID: 33071]

As humankind faces massive changes in weather patterns, sea level, ocean acidity, and oxygen levels, Scripps Oceanography has launched a new center focused on understanding and adapting to the impacts of climate change. Mark Merrifield, Director of the Scripps Institution of Oceanography Center for Climate Change Impacts and Adaptations explains how the members of this dynamic network will develop strategies for climate change adaptation.

We are on a straight-line trajectory that connects increased emissions to a much warmer and much stranger climate. Are there pathways for escaping from the up-escalator of climate change? UC Berkeley Professor Bill Collins examines the key culprits, carbon dioxide and “black carbon” from ordinary diesel combustion. Series: "Cal Future Forum: Our Changing World" [Show ID: 33068]

Dan Kammen’s Berkeley research group has revealed the need for a dramatic shift to electricity and away from both fossil and biofuels. Meanwhile, 1.3 billion people – 15 percent of the world population – still lack electricity, and their growing demand for it would raise – not lower – global temperatures. The solution, Kammen says, must be local. He sees great promise in efforts to bring together new technologies with best practices to electrify those who don’t have power and to “green it” for everybody else.

In this century, the climate is changing faster than ever. Ecologist David Ackerly has been studying how fast plants and animals may need to migrate uphill or northward as the planet warms in order to remain in their preferred temperature regime. These velocities could be as high as five miles per year -- exceeding the ability of most species to disperse and establish new populations.
